TAKE-DOWN FIREARM.

I Specification of Letters Patent.

Patented Mar. 31, 1914.

To all whom it may concern:

Be it known that we, JOHN H. VVHEELER and FREDERICK MANGLIER, citizens of the United States, residing at New Haven, county of New Haven, Connecticut, have invented certain new and useful Improvements in Take-Down Firearms, of which the following is a full, clear, and exact description;

This invention relates to tubular magazine guns of the take-down variety and of the socalled slide action type, in which the breech mechanism is controlled by an action rod capable of reciprocation in a line parallel with the barrel.

The object of the present invention is to improve the construction set forth in the Hepburn Patent No. 560,032 of May 12, 1896.

In the accompanying drawings Figure 1 is a side elevation of a gun constructed to embody this invention, the ends being broken away. Fig. 2 is a relatively enlarged view, partly broken away, of certain parts. Fig. 3 is a cross section on the plane of the line 0000 Fig. 1. Fig. 4 is a view similar to Fig. 3, butshowing the parts in a different position. Fig. 5 is a horizontal sectional view of certain details, on the plane of line 2-2. Fig. dis a view ofcertain parts shown in Fig. 1, the ends being broken away. Fig. 7 is a cross section on the plane of the line -3 Fig. 1.

1 is a barrel detachably secured to the front end of the receiver 2 by means of the usual screw-threads, part of which" may be seen in Fig. 3.

3 is a tubular magazine whichis arranged underneath the barrel 1, and supported from the barrel 1 by means of brackets 4+5, so arranged that the tubular magazine may be slid to and fro. When slid rearwardly, its rear end will enter into the forward end of the receiver, as shown in Fig. 2, thereby acting as a bolt to prevent the rotation of the barrel 1 relatively to the receiver. Any suitable latching means such as the spring stud or detent 6 may be employed to hold the magazine in its retracted or its advanced position. In the preferred form of construction, the bracket 4C is so shaped that it proj ects through a slot in the forward end of the magazine, and forms-an internal bearing, as

best seen in Fig. 7 The slot referred to is L-shaped, the widest part being at the for.-

ward end so as to form an abutment shoulder 7. The tubular magazine is provided wlth two recesses or perforations indicated respectively at 89 of a suitable size to receive the stud or detent 6. When the magazine stands in the position shown in Fig. 1, the detent 6 will project through the openmg 8 and the shoulder 7 will stand behind the ad acent part of the bracket 4 so that any forward strain on the magazine will be resisted by the bracket 4: instead of by the detent. When it is desired to advance the magaz ne, the detent 6 is depressed and the magazlne is then given a partial rotation untll the long part of the slot lines up with the adjacent part of the bracket 4, whereupon the magazine may be pushed ahead until the opening 9 registers with the detent 6, whereupon the detent will spring into said openlng, as shown in Fig. 6, holding the magazine advanced.

10 is an action rod having the usual handle 11, the rear end of the action rod being arranged to enter into the receiver 2 and make operative connection with the breech mechanism therein in any suitable way. It is preferred that the action rod 10 should also be guided by the bracket 5, as shown. The

action rod 10 preferably has a groove 10 in its side, which terminates short of its rear end (see Figs. 2 and 5).

down the gun, it is not only necessary to advance the magazine 3, which constitutes a bolt to prevent rotation of the barrel relatively to the receiver, but it is also necessary to completely withdraw the action rod 10 from the receiver, for otherwise the barthe breech mechanism (not shown) should be retained in a position within the receiver to make such operative connection, whatever it may be. To that end we provide an improved action rod holding means. In the former Hepburn patent the means for thus stopping the action rod was a loosely mounted retaining piece K having a limited sliding movement with the action rod and arranged to be pressed into a retaining notch in the barrel. This loosely mounted retaining piece is, as compared with our present improvement, relatively difiicult to operate and less satisfactory, as we shall now proceed to show, In the present instance, we provide a latch 14 pivotally mounted at 15 ina groove in the side of the forward end of the receiver. This latch 14 has one nose 16 whichis adapted to be projected into the groove 10 in the action rod when the latch stands in one position, and it has a nose 17 at the other end which is adapted to be projected into the cavity in the forward end of the receiver into which the magazine 3 is arranged to project, When the latch stands in the first mentioned position (see Figs. 1, 3 and 5) it limits the forward movement of the action rod 10 so as to prevent accidental disengagement thereof from the breech mechanism. When the latch 14 stands in the latter position (see Fig. 4), the action rod is free to be wholly withdrawn from the receiver 2. e preferably avoid the use of any retaining spring associated with the latch 14 by utilizing the magazine itself for positively holding the latch in its action rod engaging position, that is to say, when the magazine 3 is moved into the receiver and stands in the position shown in Fig. 3, it acts as a positive block against any tilting movement of the latch 14. When it is desired to take down the gun, the magazine 3 is first advanced to the position shown in Fig. 6. This mere act not only disengages the rear end from the receiver, but also leaves the latch 14 free. The latch 14 is then swung to vthe position indicated in Fig. 4, thus releasing the action rod 10, whereupon the latter may be vpulled ahead to its extreme forward position. The barrel 1 may then be unscrewed from the receiver 2.

To assemble or set up the parts of the held in the barrel-bolting position and the action rod is likewise positively held in the breech-engaging position.

It is, of course, obvious that the latch 14' constitutes an independent retaining piece which is broadly the equivalent of the in dependent retaining piece shown in the aforesaid Hepburn patent, but specifically the present improvement has many advantages thereover, some of which have herein been pointed out.

What we claim is:

1. In a magazine firearm, a barrel, a receiver, said parts being detachable by a relative rotation, a magazine arranged underneath the barrel and longitudinally movable relatively thereto, an opening in the forward end of the receiver to receive the rear end of the magazine, a reciprocating action rod arranged adjacent tothe barrel and magazine, said receiver having an opening to receive said action rod, and a latch car ried by said receiver and arranged to engage the action rod and prevent the same from being withdrawn from the receiver when said latch stands in one position and freeing said action rod when it stands in another position and movable means to engage and disengage said latch to hold it in .said rod-engaging position and to permit it to be free from said position.
